| Abstract: | The adsorption and/or decomposition pathway of Fe2(CO)9 or Fe3(CO)12 on hydrated or dehydrated NaY zeolites has been studied by an ESR technique. The adsorption resulted in the formation of three paramagnetic species withg
iso=2.0450, 2.0378, and 2.0016, which were attributable to Fe3(CO)11
–, Fe2(CO)8
–, and Fe(CO)4
– anion radicals, respectively. These radicals have been suggested as intermediates in the formation of HFe3(CO)11
– on the hydrated NaY zeolite and Fe3(CO)12 on the dehydrated NaY zeolite. |
